I have an application which is configured on IBM WebSphere 6.0 version.
In that application, where ever the System.out.printlN() Statements, are there
Where do they get printed?
I mean which log files, will get it printed?
In standalone I can check in the console, that application is deployed in windows server box
How to Identify where all the log.debug, log.info statements get printed from the application into the server box.
I tried checking in log4j.properties, but didnot find any useful info about that.
Background, we have a Websphere app server, where we have configured 2 Nodes and I am deploying in the Node 01, on my changes and trying to debug, but no help.
Please guide if any one has past exp on it.
I haven't been using WebSphere 6 lately. I newer versions you have a profile directory and a log directory within where the log file reside.
The second option is to go into the WAS administration console and go to "Troubleshooting > Logs and Trace > server_name " there you can directly view the logs. This way is documented for WAS 6.0 as well.
As others have hinted, by default the SystemOut.log and SystemErr.log files are located in each node's profiles/<profileName>/<serverName>/logs directory. (These locations and file names can be overridden in the Administration Console.)
log4j logs will depend on the appenders in your log4j configuration (could be a log4j.properties or a log4j.xml file), but might also be affected by whether anything in your application uses Jakarta Commons Logging. If it does, you may find all log4j logging also going to SystemOut.log.
It should get logged in Program files/IBM/SDP/profiles/runtimes/baseV6...
something like this .currently am at home and I don't have exact path.But search in profile directory .
You should always define your own path for appenders in your applications logging.xml instead of using default path of WAS.
The log files are resided at C:\Program Files\IBM\SDP\runtimes\base_v7\profiles\was70profile1\logs\server1

I have a Maven java project, my logging.properties is placed under resources folder. I have configured to print FINE level messages using console logger.
The WAR file generated has the properties file under WEB-INF/classes but, the application when deployed and executed, I can see only INFO level logs.
Should i initialize any LogConfiguration apart from having my logging.properties in the correct path ?
As describe here, you configure loggers in Liberty by something like this in the server.xml:
<logging traceSpecification="*=audit:com.myco.mypackage.*=debug"/>
and see the logging metatype doc to configure other aspects like log file size, number of logs to keep, etc.
Or, as the article mentions, you can use the bootstrap.properties
entries to do the same, e.g. com.ibm.ws.logging.trace.specification.
Though WebSphere also supports java.util.logging APIs, its full infrastructure isn't necessarily configured the same way as say Tomcat, which your app may be patterned after.
If you want to configure different logging behavior for different applications you can have the application Java code use a different Logger name for each, and then configure them differently through the single server.xml config (or also potentially separate the apps out onto different servers).
Dynamically changing the trace settings on a running server can be done simply by editing the server.xml config (as can dynamically configuring almost any aspect of Liberty).
My application is using Spring to handle the interaction with database (Sql Server)
And commons-logging-1.1.1.jar, log4j-1.2.17.jar, slf4j-api-1.6.3.jar and slf4j-log4j12-1.7.6.jar are put into build path for the logging framework of the application.
The last two logging jar (slf4j-api and slf4j-log4j12) are for another component inside the application to use log4j.
Here is my questions:
When Spring-Jdbc runtime excecption happens, the exception is only showed in the console of eclipse with the font color red. The exception is NOT logged into the log file. But the normal log (like log.info(...)) are all in the log file. Why can't the run-time exception be in the log file and how to solve this problem.
When I use SimpleJdbcCall to call the stored procedure with parameters in MapSqlParameterSource, the following log shows up:
14:43:30 [INFO ] Added default SqlReturnUpdateCount parameter named #update-count-1
14:43:30 [INFO ] Added default SqlReturnUpdateCount parameter named #update-count-1
......
It's really annoying because the number of this message is so large. I want to turn off this particular log message without affecting another logging with the same level (INFO)
And my log4j.xml is fine I think because the logging are basically fine except the above issues.
Spring is using commons-logging internally that's why you can see the messages in your eclipse console. To redirect commons-logging to slf4j/log4j you need to remove commons-logging-1.1.1.jar from your classpath and add jcl-over-slf4j.jar from your slf4j version. To get rid of the dublicate red eclipse messages (jul and jcl) you can set the logging level in logging.properties for the console handler to warning:
java.util.logging.ConsoleHandler.level = WARNING
Second issue was solved here.
I have a server I made in Java that needs to use a database, I chose HSQLDB.
So I have a lot of entries in my server like:
Logger.getLogger(getClass().getName()). severe or info ("Some important information");
When I run my server it goes to System.out which I think its the default configuration of java.util.logging?, so far its ok for me, and later I will make it go to a file ...
But, the problem is, when I start hsqldb it messes up with the default configuration and I can´t read my log entries on System.out anymore..
I already tried to change hsqldb.log_data=false, but it still messes up the default configuration.
Can someone help me??
I dont want to log hsqldb events, just my server ones.
Thanks
This issue was reported and fixed in the latest version 2.2.0 released today.
Basically, you set a system property hsqldb.reconfig_logging to the
string value false.
A system property is normally set with the -D option in the Java startup command for your application:
java -Dhsqldb.reconfig_logging=false ....
See below for details of the change:
http://sourceforge.net/tracker/?func=detail&aid=3195462&group_id=23316&atid=378131
In addition, when you use a fremework logger for your application, you should configure it directly to choose which levels of log to accept and which ones to ignore.
The hsqldb.applog setting does not affect framework logging and only controls the file log.
The hsqldb.log_data=false is for turning off internal data change logging and should not be used for normal databases. Its usage for bulk imports is explained in the Guide.
Try setting hsqldb.applog to 0, that shuts off application logging to the *.app.log file.
Start your server with a property pointing to the location of a dedicated properties file:
-Djava.util.logging.config.file=/location/of/your/hsqldblog.properties"
Which contains the following line to change Java logging for Hsqldb.
# Change hsqldb logging level
org.hsqldb.persist = WARNING
Side note, you can choose from the following levels:
SEVERE WARNING INFO CONFIG FINE FINER FINEST
I'm parsing gigantic Tomcat log files and I was wondering: when you stop, redeploy and then restart a Webapp, do the logs get automatically appended to the last debug.log.
More specifically: can you see in a unique debug.log file logs coming from two different deployments of a same .war?
So, for example, can you have logs from up to 11am from, say, version 1.0 of, say, example.war and then logs from 1pm coming from, say, version 1.1 of example.war in the same debug.log? Is this depending on the logger used and the way it is configured?
Tomcat will debug every error in the same log file, it doesnt matter if there is two different war files. Try using log4j (http://tomcat.apache.org/tomcat-5.5-doc/logging.html) it allows you to separate everything into different log files.
I am using Tomcat version 5.5.x. My WAR sets its own logging properties successfully and logs to $TOMCAT_HOME/logs/.YYYY-MM-DD.log. Everything that is written to my log is also written to catalina.out. Is there a way to stop the redundant logging to catalina.out stop?
Change your application's logging configuration so it doesn't log anything to the console/standard out. Tomcat redirects standard out to the catalina.out file, so if you see output in catalina.out it implies your application is writing to the console.
